The GE U20Cdiesel–electric locomotive was introduced by GE Transportation Systems as an export model in 1964. It was powered by the 8-cylinder 7FDL-8 engine. This locomotive is used worldwide with many variations and modifications. Different engines may be used, e.g. 7FDL8 and 7FDL12. Like the other members of the Universal series, it can be built to suit all track gauges.[1]
